摘要： A toothbrush with a push-back replaceable brush head includes a handle portion, a handle front section moveable inserted into the handle portion and having a supporting platform, a push mechanism including a push plate and a locking plate stacked together and penetrating through the handle front section, the push plate and the locking plate secured onto the handle portion; a brush head replaceably installed on the supporting platform, another end of the locking plate locked onto the brush head and the handle front section; wherein the handle front section is pushed toward the handle portion to allow the locking plate, the handle front section and the brush head to release from locking while the push plate pushes the brush head away from the supporting platform. Therefore, the release of locking and disengagement of the brush head can be achieved at the same time to facilitate operations of the toothbrush.

摘要： A locking structure for a replaceable toothbrush includes a locking plate and a brush head. An end portion of the locking plate includes elastic locking hooks, and the elastic locking hooks are arranged on the supporting platform. The brush head is replaceably installed on the supporting platform, and the brush head includes a brush head base and brush bristles. The brush head base includes a substrate and a surrounding plate extended from an edge of the substrate toward one side thereof, and the surrounding plate includes a locking slot for the elastic locking hook to lock thereon. The brush bristles are disposed on the substrate and extended away from the surrounding plate. Accordingly, the release of the locking and retrieval for disengagement of the brush head base are facilitated and the brush head base is firmly installed on the supporting platform.
